tion of the Benchmark Checklist located on the inside back
pages of this document.
12.1
Inspection and maintenance intervals
a
Danger
!
Risk of injury and risk of damage to prop-
erty due to neglected inspection and
maintenance!
Neglected inspection and maintenance
works or not observing the stated inspec-
tion and maintenance intervals can inter-
fere with the operational safety of the
boiler and can result in damage to property
and to persons.
>
Point out to the operator that he must
observe the demanded inspection and
maintenance intervals as a minimum.
>
Carry out proper regular inspections
once a year.
>
Carry out regular maintenance as dic-
tated by findings during the inspection
process.
a
Danger!
Danger of life and limb due to improper
inspection/maintenance!
Inspections/Maintenance work carried out
improperly can result in leakages and explo-
sion.
>
The boiler may only be inspected/main-
tained by a competent person.
All service work must be carried out by a competent person
in accordance with the Gas safety, installation and use regu-
lations. In the UK this is considered to be a person approved
at the time by the Health and Safety Executive.
In addition BS 6798: 2009 "Specification for installation
and maintenance of gas-fired boilers of rated input not
exceeding 70 kW net" advises that:
– The person carrying out a combustion measurement
must be assessed as competent in the use of a flue gas
analyser and the interpretation of the results.
– The flue gas analyser used must be one meeting the
requirements of BS 7927 or BS-EN50379-3 and be cali-
brated in accordance with the analyser manufacturers’
requirements.
– Competence can be demonstrated by satisfactory com-
pletion of the relevant ACS standard assessment, which
covers the use of electronic portable flue gas analysers’
in accordance with BS 7967, parts 1 to 4.
– The flue gas analyser is set to the correct fuel setting.
We recommend the conclusion of an inspection and mainte-
nance contract with an approved company or installer.
The inspection serves to determine the actual condition of
the respective boiler and compare it with the specified con-
dition. This is done by measuring, checking and observing.
Maintenance is required in order to eliminate any deviations
of the actual condition from the specified condition.
This normally is done by cleaning, adjustment and, if neces-
sary, replacing individual components that are subject to
wear.
You must carry out an annual inspection of the Vaillant
ecoTEC.
The annual inspection can be effectively performed without
removing components by requesting data from the DIA sys-
tem, carrying out the simple visual checks indicated in
¬ table 12.2
and performing a flue gas measurement.
The maintenance intervals and their scope are determined
by the heating engineer based on the condition of the
boiler found during the inspection.
All inspection and maintenance work should be performed in the
order specified in
¬ table 12.2
.
a
Danger!
Risk of poisoning and burning caused by
escaping hot flue gas!
Hot flue gas can escape and cause poison-
ing and burning if the boiler is operated
with an incompletely mounted or open air/
flue gas duct or if the boiler is operated
with internal leaks with the front casing
open.
>
Operate the boiler
- for commissioning
- for testing purposes
- in continuous operation
only when the front casing is fitted and
closed and the air/flue gas duct is com-
pletely mounted.
>
Exclusively for test purposes such as gas
working pressure testing you can operate
the boiler may be operated with the front
casing removed for short durations ONLY
but must have a completely mounted air/
flue gas duct.
12.1.1 General inspection and maintenance
instructions
To ensure the faultless operation, long term availability of
all functions and long working life of your Vaillant boiler
and to prevent modifications to the approved series status
only genuine Vaillant spare parts must be used when carry-
ing out inspection, maintenance and repair work.
